i am starting to use django and i have a little mistake in some of my code but i dont know where is it.
I am trying to load a image from my database in a filepath.
This a part from my models.py that i am using to load the image:
class Articulo(models.Model):
...
nombre_imagen=models.CharField(max_length=64)
As you can see, i am loading the image from a filepath in my database.
And this is the part of the code that i am trying to do that:
{% if articulo %}
{% for articulo in articulo %}
....
<img class="card-img-top" img src="{% static '{{articulo.nombre_imagen}}'}" alt="">
.....
{% endif %}
The image is located in the static files:
STATIC_URL = '/static/'
I think there is a stupid problem, but as i said before. I am new at django.
I hope that anyone can help me, thank you!.
Your issue is that you aren't calling the image variable correctly.
src="{% static '{{articulo.nombre_imagen}}'}"
should be
src="{% static articulo.nombre_imagen %}"
Also, your image field should be models.ImageField().
nombre_imagen=models.CharField(max_length=64)
should be
nombre_imagen=models.ImageField(upload_to="images/", blank=True)

I am trying to store images on a database and then display them on a Django template. For some reason Django is only showing the alt (alternate - html attribute) instead of the actual image.
This is the template
{% extends "myapp/layout.html" %}
{% load static %}
{% block body %}
<div class="sidenav">
Gallery
About
Contact
</div>
<div class="main">
<h2>Gallery</h2>
{% for image in images %}
<img class="gallery" src="{% static '{{image.image.url}}' %}" alt="{{image.description}}">
{% endfor %}
</div>
{% endblock %}
This is my model
from django.db import models
# Create your models here.
class Image(models.Model):
image = models.ImageField(upload_to='images/')
description = models.CharField(max_length=50)
def __str__(self):
return "Description of image: " + self.description
This is what I'm seeing
These are normally media urls, so you render these with:
<img class="gallery" src="{{ image.image.url }}" alt="{{image.description}}">
You need to add the views regarding media files to the urlpatterns, as described in the documentation.
or if these really only contain a path relative to the static folder, you work with:
<img class="gallery" src="{% static image.image.url %}" alt="{{image.description}}">
But it is not very likely that this is the case.
Regardless what the Note that Django only serves static/media files in debug mode (DEBUG = True). If you run this on production, you will need to configure apache/nginx/… to serve static/media files.
I am currently learning Django and making my first steps. I try to build a webgallery to learn all the basic stuff. I successfully displayed some images using static files. So I tried saving Images through ImageFields and "upload_to" in my DB, saving it to my static directory. I tried to display everyone of them with a for loop in an tag. My img displays properly with using a {% static %} tag but when I try to insert a {{ }} Tag it isn't working, although it's the same url it doesn't work.
I tried changing my STATIC FILE in settings.py
I tried various other forms of nesting my {{}} in there
Reading the docs to staticfile https://docs.djangoproject.com/en/2.2/howto/static-files/
This thread Display an image located in the database in Django
This thread https://docs.djangoproject.com/en/2.2/topics/files/#using-files-in-models
My Code:
<p>Overview</p>
{% block content %}
<div>
{% for image in images %}
{{ image.img_photo }} <!-- webgalleries/test.jpg -->
{% load static %}
<img src="{% static 'webgalleries/test.jpg' %}" alt="{{ image }}"> <!-- working -->
<img src="{% static '{{ image.img_photo }}' %}" alt="{{ image }}"> <!-- not working -->
{% empty %}
<p>No content</p>
{% endfor %}
</div>
{% endblock content %}
I expect the output to be an img from my static directory.
A hint, some advice or other forms of help is highly appreciated.
Thank you so much!
okay if you want to display images from database you should do these steps :
1- go to your settings.py and write this code there ,
MEDIA_ROOT= os.path.join(BASE_DIR,"media")
MEDIA_URL= "/media/"
2- then create new folder in your project called 'media' and create folder inside 'media' called 'images' (finally result will be like this 'media/images' )
3- go to your model.py in your class that having 'img_photo'
and you should write the model like this
class Images(models.Model):
img_photo = models.ImageField(upload_to='images/',null=True, blank=True)
def get_image(self):
if self.img_photo and hasattr(self.img_photo, 'url'):
return self.img_photo.url
else:
return '/path/to/default/image'
def __str__(self):
return self.img_photo
4- go to admin.py then write :
from yourapp.models import Images
then add this line below
admin.site.register(Images)
then open your terminal or console and write :
1- python manage.py makemigrations
2- python manage.py migrate
5- in html code you must write :
{% for image in Images %}
<img src="{{ image.get_image }}" >
{% endfor %}
go to admin panel and upload any photo for test
I am trying to get all image link present in a folder. Currently, I am assigning the link manually. But, I want my django to get all images from a specific folder irrespective of their names.
<li>
<img src="{% static "styles/jamia/1.jpg" %}">
</li>
<li>
<img src="{% static "styles/jamia/2.jpg" %}">
</li>
I am looking for something like:
{% for file in {% static "styles/jamia/" %} %}
<img src="{{file}}" alt="">
{% endfor %}
All images are present in jamia folder.
This isn't something Django has built in. But Django is just Python, and you can use normal Python file functions to get your list in the view:
files = os.listdir(os.path.join(settings.STATIC_ROOT, "styles/jamia"))
This seems to have been answered in parts before, but probably requires some searching for all the answers. So in an attempt to provide a complete answer to this questions in one place:
In views.py you would want to do something like the other answer says:
context_dict = {}
files = os.listdir(os.path.join(settings.STATIC_DIR, "styles/jamia/"))
context_dict['files'] = files
return render(request, 'home.html', context=context_dict)
Then in your html template you can loop over your images. In addition, we make use of with to join the root to the static file with those names pulled out in the views.py, but you could have concatenated the whole path in views and not needed with. So, in home.html:
{% for file in files %}
{% with 'images/'|file as image_static %}
<img src="{% static image_static %}" alt="">
{% endwith %}
{% endfor %}
I'm trying to use django's static templatetag to display an SVG, but it doesn't seem to recognize the SVG as a valid image url. This is what I currently have:
settings.py
import mimetypes
mimetypes.add_type("images/svg+xml", ".svg", True)
landing.html
{% load staticfiles %}
<img src="{% static 'images/right-arrow.svg' %}" />
At least in my view.py, it recognizes the SVG mimetype:
views.py
print(mimetypes.guess_type(static('images/right-arrow.svg')))
# returns ('images/svg+xml', None)
The SVG does display in a non-django page, and it will download the SVG if I try to open the SVG path in a new browser tab.
I'm currently using python 3.4 and django 1.8.4.
I found the issue. In settings.py, it should be mimetypes.add_type('image/svg+xml', '.svg', True). image should be singular.
I faced a similar issue.I would recommend you to use :
src="{{ STATIC_URL }} images/right-arrow.svg" instead of src="{% static 'images/right-arrow.svg' %}"
svg format might not always identify django's method of obtaining staticfile contents.Hope this helps :)
Add this in your settings.py file.
import mimetypes
mimetypes.add_type("image/svg+xml", ".svg", True)
mimetypes.add_type("image/svg+xml", ".svgz", True)
In your cases you have added images in add_type which should be singular (image).
You are loading staticfiles and using static?
This is wrong.
Try changing {% load staticfiles %} <img src="{% static 'images/right-arrow.svg' %}" /> to
{% load static %} <img src="{% static 'images/right-arrow.svg' %}" /> and you also need to consider which app you should find your static files.
please help bring images into the template
in django1.6 I uploaded via the form in the database image. screenshot. ( checked that the images loaded in a specific directory ) . then imported into the template file settings.py variable BASE_DIR and to all records of a table . then tried in the template to display the image as follows:
{% for entrie in all_entries_carousel %}
<a href="{{ entrie.link }}" title="{{ entrie.title }}" target="_blank">
<img src="{{ BASE_DIR }}/{{ entrie.image }}" width="300" height="200" alt="{{ entrie.title }}" />
</a>
{% endfor %}
results in images that I have not loaded and displayed.
in the source path
c:\Python33\django_projects\proj1/carousel/media/images/img1.png
please tell me how can I still display the image. Sure , there is a path without importing BASE_DIR
ps this way does not work proj1/carousel/media/images/img1.png
You need to configure your static files.
From Django docs:
Make sure that django.contrib.staticfiles is included in your
INSTALLED_APPS.
In your settings file, define STATIC_URL, for example:
STATIC_URL = '/static/'
In your templates, either hardcode the url like
/static/my_app/myexample.jpg or, preferably, use the static template
tag to build the URL for the given relative path by using the
configured STATICFILES_STORAGE storage (this makes it much easier
when you want to switch to a content delivery network (CDN) for
serving static files).
{% load staticfiles %}
<img src="{% static "my_app/myexample.jpg" %}" alt="My image"/>
Store your static files in a folder called static in your app. For
example my_app/static/my_app/myimage.jpg.
